I've got Dunlap DA2's (I think) and get over 30 MPG on the highway (highest recorded was 32.02 MPG). In town is never less than 24 MPG, and it's as stop and go as you can get. Even when I drive it with a pretty heavy foot I still get 24 MPG. I love this car for that. I think synthetic motor oil and the intake contribute to the mileage, and I know upgraded plugs and wires on the ignition side help a bit also. I wonder what improvement the X1's will do for my car?
